Definitions
- the invention relates to a positioning device for joining two components in a predetermined relative position, wherein each component has a central axis at the corresponding positioning point and the axes are to run coaxially when eugging.
- one of the components is a machine table, the other is an interchangeable pallet or one component is a clamping base and the other is a workpiece to be clamped, etc.
- the object of the invention is to further develop the positioning device of the same type in such a way that, despite the large positioning diameter, only moderate joining forces have to be applied.
- Large positioning diameters are preferred because, for example, they have large openings can be provided for clamping devices because high transverse axial positioning forces can be derived and because the inevitable wear is low and the repetition accuracy of the positioning is high.
- the dimensioning of the parts of the components that can be deformed by the mountains must be done according to the individual case, taking into account the mass of the component to be positioned, the wedge angles defined by the tapering of the positioning element and depressions, the coefficients of friction and others.
- the areas of application of the new positioning device are primarily those tasks where components have to be inserted into specified relative positions with ultra-precision, i.e. in the 0.001 mm tolerance range.
- the latter task is present, for example, when a device base plate or a workpiece (for example, according to FIG. 5) is always very accurate in the repetition of the joining process prescribed relative position should be positioned.
- the joining process is preferably carried out in such a way that, after the components have been placed one on top of the other, the clamping force F is initially applied completely only at one positioning point, for example the right one, which brings about a clear coincidence of the center axes of the two positioning recesses at this point.
- the full clamping force F is subsequently applied to the left positioning point, the omnipresent tolerances are compensated by asymmetrical deformations of the contact zones, but the exact centering effect in the direction of a perpendicular to a connecting line between the two positioning points is maintained. This effect is also favored by the combination of the design features according to claim 1.
- FIG. 1 is an axial section through a clamping device with an exchangeable pallet with a positioning device according to the invention, the clamping position being shown on the left and the unclamping position on the right,
- FIG. 2 a, 2 b show the basic positioning principle with the interacting parts before and after joining.
- FIG. 3 shows in axial section a positioning device according to the invention in a configuration suitable for universal use.
- FIG. 4 shows another embodiment of the positioning device with only one axially displaceable positioning recess.
- Fig. 5 shows in section a structural unit from a clamping base with a clamped workpiece
- Fig. 6 shows in section a structural unit from two tool halves.
- FIGS. 2 a, 2 b The basic operating principles of the positioning device according to the invention are illustrated in FIGS. 2 a, 2 b, of which FIG. 2 a shows the situation before clamping and FIG. 2 b the situation after clamping.
- the two components 100 and 102 are to be centered with respect to an axis 104 which runs through the center of the ball lo6.
- Each component 100, 102 is provided with a positioning plate 108 or 110 of different construction, each of which is inserted into a corresponding hole in the component concerned.
- the plate 108 is actually only a perforated disc, supported near its outer circumference by a shoulder of the component 100, while the plate 110 is cup-shaped with a central perforation in the base and is supported with the free edge of its edge.
- the ball 106 is pierced and penetrated with play by a clamping screw 112 which can be screwed into the component 102 and presses with its head onto the opposite outer surface of the component 100.
- the ball diameter that can be defined by contact zones 122, 128 of the positioning recesses 124, 126 in the positioning plates when the joining surfaces 116, 118 are in contact with the ball removed has an undersize with respect to the ball 106, so that before tightening the screw, as in FIG. 2 a shown, a gap 114 is present between the mutually opposite joining surfaces.
- the parts 106, 108 and 110 are elastically deformed, namely the ball 106 by compressive stresses and the plates 108 and 110 by compressive and - mainly - bending stresses, the distribution of the deformation components by the designer by appropriate choice of Dimensions can be made.
- the modulus of elasticity of the materials used also plays a role, as does the coefficient of friction between them and the profile of the positioning recesses and the selected contact area of the ball 106 (closer to its equator or closer to its poles). It has been shown that even with ball diameters of 60 mm, a repeatability of the centering in the order of magnitude of 1 micron and smaller, it is achievable without a disproportionately high clamping force.
- the contact zones of the ball as the positioning element which are relevant for centering are identified by 120, 130.
- FIGS. 3 and 4 show positioning devices which can be used in a very general manner, for example in the field of mechanical engineering or device construction.
- the positioning devices have been realized through the interaction of standardized components.
- the ones carrying the positioning recesses 328, 418 and on their membrane-shaped parts in axial direction device deformable components are designed as press-fit "positioning inserts".
- These standardized positioning inserts are provided with hardened and ground surfaces on the outer diameter and on the positioning recess and have a press-in phase on the outer cylinder.
- FIGS. 3 and 4 correspond to those in FIG. 2b, ie the two components 300 and 302 to be positioned in an exact relative position are clamped together by a clamping force F on their joining surfaces 324 and 326 after a joining gap (similar to 114 in FIG 2 a) has been eliminated while deforming the plate-shaped part of the positioning inserts 304 or 404 (in FIG. 4).
- the depth of the positioning inserts 304 pressed into the bores 312 can be predetermined or changed by screw inserts 308.
- a hexagon socket 310 enables a screw movement to be generated.
- the press fit of the positioning insert 304 ensures a concentric fit of the positioning recess 328 relative to the component bore 312 through freedom from play and at the same time ensures good transverse axial rigidity of the positioning insert.
- a threaded bolt 314 is welded on, which is in engagement with a nut 316 which is supported against disc springs 318. Falling out of the plate springs and nut is prevented by 2 locking rings 320, 322.
- the positioning insert 404 sits with the plate-shaped component 420 having the positioning recess 418 on the floor 408 of the component bore 410.
- the positioning element 406 has a spherical, but preferably spherical, shaped contact zone 416 projecting beyond the joining surface 324 and a cylindrical part 414 with which it is pressed into the receiving bore 412 of the component 302.
- a nozzle 426 is inserted, the inner bore of which is connected to a compressed air source, not shown.
- test air can be let in through the nozzle 426 into the now closed interior of bore 410 in order to be able to conclude that the positioning process has been carried out correctly by means of the tightness to be tested.
- Figure 1 shows a device for centering and clamping a change pallet with respect to a clamping device axis.
- the 1 comprises a base 10, the axis 12 of which represents the reference axis.
- the base is fixed on a machine table or a straightening system; the corresponding fastening means are not shown since they are familiar to the person skilled in the art and do not form part of the invention.
- the base 10 is hollow, and a clamping head 18 is mounted in it practically free of play by means of high-precision preloaded roller bearings - a radial bearing 14 and a front bearing 16 - about the axis 12.
- a worm ring 20 is screwed onto it, with which a worm 22 is engaged; the screw 22 protrudes from the base 10 and can e.g. be turned using a hand crank.
- a clamping plate 24 is screwed to it, into which a positioning plate 26 is inserted; the positioning plate 26 can be aligned radially with respect to the axis 12 and then firmly screwed to the clamping plate by means of screws 28.
- the positioning plate has a central conical opening 30 in which a positioning ball 32 lies; a retaining ring 34 screwed together with the positioning plate rests with a lip on the ball 32 above its diameter and prevents the ball from being pulled out when the pallet 36 is removed or also assumes a sealing function.
- the positioning plate is aligned with the pallet removed by moving the ball close above the retaining ring 34 with a stationary probe head and rotating it the ball of the clamping head with respect to the axis 12; then the screws 28 are tightened.
- the clamping plate 24 has a collar 38, by means of which the pallet 36 is roughly positioned radially, and a projecting pin 40, by means of which the pallet is positioned in the circumferential direction; only rough positioning is required here. If the roughly positioned pallet is lowered from its preparatory position - on the right in FIG. 1 - onto the clamping plate, a conical central depression 42 of the pallet comes into contact with the ball 32 and is centered by it precisely with respect to the axis 12.
- the pallet carries clamping means 44, e.g. T-slots for fastening a workpiece, such as a gear wheel, the position of which can also be centered with respect to the axis 12 by means of a probe.
- the pallet with the workpiece clamped so precisely centered can then be removed and placed on a processing station on an identically constructed device, the ball of which ensures centering with respect to a machine axis.
- the clamping head 18 has a multiply graduated central bore, which serves as a hydraulic working cylinder and receives a piston 46.
- the two cylinder spaces 48 and 50 are through the clamping head through holes 52, which open into annular grooves 54 of the base, and through the base lo through holes 56, which lead to the outside (not shown), with pressure oil, so as to the piston in the axial direction relocate.
- the upper cylinder space 48 is sealed off by a cap 58 which is penetrated by the upper piston rod 60.
- the lower piston rod 62 carries a pinion 64 which meshes with a toothed rack which is formed on a piston 66 which extends tangentially with respect to the pinion; the piston can also be displaced hydraulically in both directions by actuation with pressure oil in order to rotate the piston 46 by a predetermined angle of, for example, 30 °.
- the upper piston rod 60 carries on a shoulder a support plate 68 on which a number - e.g. Four - support bolts 70, which slide through corresponding holes in the clamping plate 24. If the cylinder space 50 is fed with pressure oil (FIG. 1, right), the bolts 70 lift off the pallet 36, while in the lowered position of the pallet (FIG. 1, left) they are a short distance from the underside of the pallet, since the pallet is then comes to sit on the collar 38.
- a number - e.g. Four - support bolts 70 which slide through corresponding holes in the clamping plate 24.
- the free end of the upper piston rod 60 passes through a central through bore of the ball 32 with play, and at its end a clamping nut 72 is screwed on, on the periphery of which with a pitch of e.g. 30 ° clamping claws 74 are shaped like a star.
- a clamping bush 76 is embedded, which carries inwardly projecting counter claws 78. If claws and counter claws face each other, the pallet 48 can be pulled down and tightened by actuating the cylinder space 48; if claws and counter claws are in a gap, the pallet can be removed. The change between these two positions is carried out by actuating the piston 66, whereby the piston 46 and with it the upper piston rod are rotated.
- the lower piston rod extends with its free end through a seal into a chamber 80 of a bushing 82 which is fastened in the base of the base; the chamber can be supplied with compressed air, which then flows through a central bore 84, which passes through the lower piston rod, the piston 46 itself and also the upper piston rod 60 and opens at the ends thereof. In this way, the conical depression 42 can be blown free of chips and the like when the pallet is raised.
- the piston travels even further downward and tensions the pallet and the clamping plate 24 against one another via the interaction of the claws 74 with the counter-claws 78, so that finally the pallet on the joining surface, namely the upper side of the collar 38 of the clamping plate, deforms the components involved 24, comes on.
- the clamping force exerted by the piston is converted in the contact area between ball 32 and indentation 42 into predominantly compressive stresses, in the contact area between ball 32 and the conical opening 30 of the positioning plate 26 partly in compressive and partly in bending stresses, since the positioning plate can deflect downwards (this Deflection is low, approximately in the 0.1 mm range, so that it is not shown in the drawing in the left part of FIG. 1).
- the positioning element 32 shown as a ball can of course also be designed differently. For example, it is possible to firmly connect the ball 32 to the positioning plate 26. Both parts can also be replaced by a single part, in which the positioning element is molded onto the plate 26 and is formed as part of a ball only in the region of the contact zone.
- Deviations from the ideal spherical shape to a small extent would be permissible - if only with regard to the ubiquitous manufacturing tolerances - but worsened the positioning result under certain operating conditions.
- FIG. 5 shows an advantageous application of the positioning device according to the invention in connection with the positioning of workpieces on clamping bases.
- a component 502 to be machined is positioned relative to the mounting base 504 by means of two positioning devices 544, 546 and clamped with its mounting surface 548 under the action of clamping forces symbolized by arrows F against the mounting surface 550 of the mounting base.
- the central axes of the positioning devices brought into coincidence by means of the spherical positioning elements 528, 530 are identified by the lines 512, 526.
- the two positioning devices are shown composed of different components. Left are in the upper, as in the lower part in the receiving holes 522, 536 positioning inserts 524, 538 used (similar to part 404 in Fig. 4), which form the actual positioning 540, 542 with their central bores.
- the positioning recess is formed in the lower part on the positioning insert 534 and directly molded into the component 502 in the upper part.
- the clamped component 502 could be any workpiece.
- the component 502 is one which belongs to the species of the standard parts, which are pre-processed to a certain extent by the standard parts manufacturer and which subsequently be reworked by the user to produce the final shape.
- Subsequent processing e.g.
- the production of a cylindrical recess 520 which is central to the center axis 516 usually takes place by several successive work operations (e.g. milling, eroding, grinding) on different work machines.
- each operation requires a precise measurement of the machining features created in the previous operation. It may also be necessary for the processing features to be created by the user into one exact reference to the dimensions already created by the manufacturer, e.g. hole 508.
- the positioning recesses 540, 518 already made by the manufacturer have the task in the course of further processing for the user to carry out an exact alignment of the component with each new work operation and to serve as a reference material measure for the dimensions to be produced during the operation.
- the clamping pad 504 can be different, which can always remain on the same processing machine.
- the measuring system of the processing machine is advantageously always precisely related to the clamping base, for which purpose e.g. the center axis of the positioning inserts 538, 534 can be used.
- the machine measuring system is thus automatically aligned precisely relative to component 502.
- the positioning recess 518 can be made directly in the component body.
- a spherical cap-shaped design of the contact zones is advantageous.
- Another possibility for saving costs is that the standard component 502 initially only has receiving bores 522, into which the positioning inserts 524 with the actual positioning recesses 540 are subsequently inserted (pressed), the positioning inserts 524 being reusable several times.
- the clamping pad 504 will usually have a plurality of positioning recesses in order to accommodate components of different sizes.
- the center axes are preferably located. the positioning recesses of the component and the mounting base on the crossing point of grid lines of a standard grid.
- FIG. 6 shows the use of a positioning device on an injection molding tool for extremely precise centering of the two mold halves 602 and 604.
- the positioning device 628 and the guide column 608 are only shown once in the drawing, although both are each present twice.
- the guide columns 608 are inserted with undersize in the guide bores 612. They take over the guiding of the upper mold half when opening the tool for ejecting the injection molded part 606 and also when closing the tool as a pre-centering for the positioning process which begins only in the last phase of the closing path through the positioning devices 628.
- the positioning devices 628 have Positioning inserts 616, 620, of which only part 616 has an axially deformable plate-shaped component.
- the forces symbolized by the arrows F can be generated not only by mechanical clamping elements by hand, but also by vacuum, magnetically, electromagnetically, hydraulically or by other means.
